Recharging a Dead Battery
courtesy of Bob, The Auto Answer Man
Is it harmful to a vehicle's alternator to rely on it to recharge a completely dead battery after a jump start? It seems to me that a completely drained battery could place too great a load on the alternator and possibly damage its diodes. Thanks in advance for your answer.
An alternator was never meant to recharge a dead battery. It was only meant to supply the vehicle for power needed to operate and what little was left over to be sent back to the battery. Incidentally, it is a good idea to put a good working battery on slow charge for awhile to top it off. I have done this on all my new cars and have extended the life of the original factory battery to over 6 years.
